"The digital nature of the project required a digital device to present to Her Majesty, and The Queen will be able to press 'play' on the tablet before watching a video of some of the best Jubilee time-capsule entries," said Danny Sriskandarajah, director of the Royal Commonwealth Society charity.

The organisation said it had at one point considered using an Apple iPad, but ultimately opted for Samung's tablet after discussing the project with both firms.

The device will be stored at Windsor Castle as part of the Royal Collection.

It already includes other digital products - such as PCs and DVDs - as well as art, furniture and other memorabilia spread across 13 residences. It is held in trust by the Sovereign for her successors and the nation.
